Inhaled anaesthetics can be used in mechanically ventilated critically ill patients to provide sedation. This approach to sedation potentially improves patient and health system outcomes, but further supportive evidence is needed. The objective of the SAVE-ICU clinical trial is to compare the effectiveness of inhaled versus intravenous sedation in ventilated adults with acute hypoxaemic respiratory failure.

SAVE-ICU is a multicentre, open-label, pragmatic, randomised controlled trial conducted in 15 intensive care units (ICUs) in Canada and the USA. Eligible patients include mechanically ventilated and sedated adults with acute hypoxemic respiratory failure from COVID-19 or non-COVID causes with PaO₂/F_IO₂ ratio 12 hour). A hierarchy of outcomes was identified at the time of trial design, as the trial was launched during the COVID-19 pandemic when study drug shortages, staffing challenges and healthcare system pressures were prevalent and there was a requirement for rapid evidence generation and implementation on this topic. The primary outcome and highest in the hierarchy is hospital mortality (requiring 758 participants). Secondary and lower hierarchical outcomes are ventilator-free days at day 30 (200 patients), quality of life at 3 months (144 participants) and ICU-free days at day 30 (128 participants). Additional secondary outcomes include median daily oxygenation at day 3 (PaO₂/F_IO₂ ratio), need for adjunctive acute respiratory distress syndrome therapies (prone positioning, inhaled nitric oxide, paralysis with a neuromuscular blocking agent and extracorporeal membrane oxygenation) during ICU stay, days alive and free from delirium and coma at day 14, hospital-free days at day 60 and disability score at 3 months and 12 months after enrolment.

The protocol was approved by all hospital ethics committees and by Health Canada. Informed consent will be obtained from substitute decision makers or deferred consent (as permitted by site ethics board). Trial findings will be shared at the end of the study using peer-review publications, conference presentations and social media as part of the trial knowledge translation plan.

Recurrence of hypertriglyceridaemia-associated acute pancreatitis (HTG-AP) is common. Uncontrolled HTG after hospital discharge is an important risk factor for recurrence. However, the optimal triglyceride (TG) goal of lipid-lowering therapy for outpatients remains unclear. The efficacy and safety of intensive TG-lowering therapy on reducing recurrence of HTG-AP trial aims to determine whether intensive TG-lowering therapy (with a TG goal of

This is an investigator-initiated, multicentre, open-label, parallel, superiority, randomised, controlled trial. Adult patients who have been successfully treated and discharged from their index episode of HTG-AP will be screened for eligibility after a 4-week to 3-month run-in period in the outpatient setting, and then patients with the fasting serum TG levels ≥150 mg/dL at baseline are eligible. During the study period, a total of 256 study participants will be randomised to receive either intensive TG-lowering therapy or usual care. In the intensive TG-lowering therapy group, the goal of TG levels is lower than 150 mg/dL, which will be monitored at 1 month, 3 months, 6 months, 12 months and 18 months after randomisation. In the usual care group, the goal of TG levels is lower than 500 mg/dL according to the current guidelines. Lifestyle suggestions and TG-lowering agents are the main strategies to manage the lipid level. The primary endpoint is the incidence of recurrent episodes of HTG-AP at 18 months after randomisation.

This study has been approved by the Ethics Committee of the First Affiliated Hospital of Nanchang University (No. 2023101–3). Ethics approval of each participating centre is required before initiation of enrolment. The results of this study will be published in peer-reviewed journals and reported at international conferences.
